Comparative Study Between Geopolymer and Ordinary Concrete Regarding Compressive and Flexural Strength in RC Beam and their Environmental Sustainability Assessment for Construction

Abstract

In this study, the compressive strength, flexural strength, and bond behavior of geopolymer and regular Portland cement (OPC) concrete are compared in reinforced concrete (RC) beams. The principal binder of geopolymer concrete is industrial by-product such as fly ash, and it provides an ecologically benign and sustainable substitute for regular OPC concrete. According to the research, geopolymer concrete is a potential material for structural applications because of its better qualities, which include increased compressive strength, improved durability, and enhanced resistance to sulfate, acid, and high temperatures. In contrast to OPC concrete, geopolymer concrete has better mechanical qualities, a reduced carbon footprint, and increased durability when combined with reinforcing steel bars to form strong and long-lasting structural elements in RC beams. The study emphasizes how crucial it is to comprehend the characteristics and behavior of geopolymer concrete in RC beams in order to help build ecologically responsible and sustainable infrastructure. This research offers important insights into the possible applications of geopolymer concrete in the construction industry, which may help lessen the environmental effect of concrete manufacturing and promote sustainable growth, by comparing the performance of geopolymer concrete with OPC concrete.
